Air & turbo
Charge pipe
Carries pressurized air from the turbo toward the engine.
Between turbocharger, cooler and intake assembly.
The pipe, joints and seals must contain boost while accommodating heat and movement.
A pressure hose between an air pump and its destination.
A split pipe or failed seal may cause hissing, reduced boost or mixture faults.
Filters follow the vehicle service schedule; ducts and boost hardware are inspected for condition, sealing and operation.
A hose or filter is generally simpler to service than a turbo assembly. Access and diagnosis can dominate cost.
A charge pipe carries boosted intake air; a downpipe carries hot exhaust.
BMW combustion models; boost hardware applies to turbocharged engines only.
